I have 4 kinds of sun chokes,Pink Crispy & Stampede being two.
They came from http://www.oikostreecrops.com.
Asparagus, rhubarb,garlic & onions, cardoon, lovage,Rosemary,crosnes or Chinese artichoke & Poke weed are perennials, too. Onions & garlic do not have to be lifted or harvest every year, lovage & Rosemary are herbs also. Peppers & tomatoes are perennials in frost free zones.
I have the Jerusalem artichoke or sun choke, the Flower with vegetables, because it is nice plant, that is good to eat.

Wow what a collection! I’m growing garlic right now and am really interested about the garlic you have there.
What happens if you just leave it in the ground? Does the bulb rot after a while and then replaced by another? Please share your knowledge.
